Calculator data

The chmod calculator runs in your browser. Permission values entered into the tool are not sent to a chmodtool.com server.

Analytics

We use Cloudflare Web Analytics to understand aggregate site traffic and page performance. Cloudflare states that Web Analytics does not collect or use visitors' personal data.

We also offer optional Google Analytics 4 measurement. Google Analytics is not loaded unless you select "Accept analytics." When accepted, it measures page views and successful uses of the copy command button. The copy event records whether the octal or symbolic command was copied; it does not send the command text, filename, or permission value entered into the calculator.

Google Analytics may use cookies and process information such as browser and device details, approximate location, referring pages, and interactions with this site. Google processes this information as our analytics provider. You can decline analytics on your first visit or change your choice at any time through "Analytics settings" in the footer. Your choice is saved in your browser's local storage. If you withdraw consent, we stop sending new Google Analytics events and remove Google Analytics cookies accessible to this site.

Advertising

Advertising is not currently enabled, and this site does not load advertising scripts. This policy will be updated before advertising is enabled.
